To all whom it may concern.

Be it known that L-MAX E. Mnmoma citizen of the United States, residingin Washington, District of Columbia, have invented certain new anduseful Improve- -ments in Typewriting-Machines, of which the followingis a specification.

This invention relates to typewriting machines and more particularly topaper-roll carrying means for the same.

In machines of this character, it is sometimes desirable to provide thework-sheets in the form of a continuous web of paper These webs are fedtogether into the machine and around the platen to receive typeimpressions. The sheets or webs may be superposed with webs of carbonpaper or with inking ribbon at the printing line of the machine.

In practice, it is frequently desirable to use paper of differentwidths, at different times, and also to write at different positionsalong the platen, and accordingly, the mechanism for holding the rollhas been made adjustable so as to accommodate paper of various widthsand so as to be adjustable lengthwise of the platen; and, where apluralitv of rolls were used, such changeshave requiredthe adjustment ofeach individual holding means for each individual roll. I

have found it advantageous to provide supporting means having individualsupports or journals for the several rolls, sald supporting means beingadjustable to eilect a simultaneous adjustment of the journals for. allthe rolls. These means may comprise a set of roll-carrying studs mountedon a pair of side-plates, adjustably mounted in the roll-support properso that by adjusting either or both the side plates, all of the studs oneach plate will be moved together, thereby changing the width betweenthem. These side-plates may be slidably mounted on a roll-carrying frameproper and adapted to be held in adjusted position by said screws.

' This construction permits a frame to be built of a size which willexactly adjust itself to a standard typewriting machine,

and also permits the webs or rolls to 'be adjusted along said supportfor the purposes mentioned above.

This application is a division of my copending application Serial Number93,575, filed April 26, 1916.

Other features and advantages will hereinafter appear.

In the accompanying drawings:

Figure 1 is a part sectional end elevation of a typewriting machine,with the present invention applied thereto.

Fig. 2 is a part sectional elevation on a larger scale, partlydiagrammatic, showing the websfed around the platen.

Fig. 3 is a plan view showing the construction of the roll holding stubshaft.

Fig. 4 is a rear elevation of the machine.

The invention is shown as applied to an Underwood typewriting machine.Keys 10, fulcrumed at 11, operate through bell cranks 12 to swingtype-bars 13 upwardly and rearwardly about a fulcrum 14 and cause thetypes 15 to strike against the front face of the roller platen 16. Theplaten axle 17 is' ournaled in the ends 18 and 19 of the platen frame,the latter also including an inclined paper shelf 20 connecting theframe ends, said shelf located at the rear, of the platen for supportingand guiding the work to the platen.

The platen may be rotated by hand Wheels 21 on the platen axle. Theline-spacing mechanism for rotating the platen to linespace the work,comprises a hue-space lever 22 (Fig. 1), operable to move rearwardly aslide 23 carrying a driving pawl'24 to drive a line-space ratchet wheel25 fixed to the platen axle, to thereby effect line-space r0- tations ofthe platen. The platen frame is mounted on a carriage 26, beingshiftable up and down thereon to upper-and lowercase positions, by meansof the usual platen shifting mechanism. The carriage is mounted totravel horizontally on front and rear guide rails 27 and 28, and isdriven in lettor-feed direction by the usual spring drum 29 (Fig. 4)connected through a band 30 to the carriage.

The letter-feed movements of the carriage are controlledby the usualmechanism, comprising a rack 31 (Fig. 1) on the carriage'running in meshwith an escapement pinion 32 which drives an escapement wheel 33 with.which cooperate escapement dogs 34 on a dog rocker 35. The dog rocker isactuated by a universal bar 36 which, at each type stroke, is moved rearscribed may be those usual to the commercial Underwood typewritingmachine.

The paper strips or webs 40 on which manifolding is done are wound onsupply rolls 41 removably mounted on a truck 42 arranged to travel withthe carriage. As shown, the truck comprises a frame having openrectangular frame ends 43 connected by tie rods 44 extending between thecorners of the frame ends. The skeleton frame thus constructed is strongand-rigid and at the same time is light in weight and has littleinertia, so that it does not materially impede the letter-feed movementsof the carriage.

The rolls 41 are supported between plates 45 mounted on the rods 44 andadjustable lengthwise of the rods, permitting adjustment of said platesto rolls of different lengths, and also permitting adjustment of therolls to any desired position lengthwise of the platen. The rods 44 mayextend through collars 46 fixed to said plates, and provided with setscrews 47 by which the plates may be clamped'in their adjusted positionson said rods. The paper rolls 41 may be mounted on spools or cores 48(Fig. 4). Each spool is provided at each end with a central bore orsocket to receive stub shafts 49, on which the spool is journaled, saidshafts 49 being mounted for endwise movement in the plates 45, into andout of spool-holding position. Said stub shafts may be slidable endwisein bearing sleeves 50 fixed in the plates 45 and each provided with abayonet slot 51 in which works a pin 52 on the shaft, whereby said shaftmay be locked in its spool-holding position. With this construction anyroll may be quickly placed in position or removed without interferencewith the other rolls.

The roll-holding frame or truck is arranged to travel with the carriage26, so that the rolls may be maintained in operative relation to theplaten. For this purpose the truck 42 is mounted to travel on a trackcomprising an angle-bar 53 located behind the main frame .54 of themachine. Said track is removably mounted on the machine frame by meansof brackets 55 which are rigidly connected with the track 53 byhorizontal arms 56. The track may be removed from the machine by simply'lifting the brackets 55 off the machine frame. The weight of theroll-holding frame is supported on truck wheels 57 which run on thetrack 53. Said wheels are prevented from moving rearwardly off the trackby a guard rail 58. Horizontal forward ends with hooks 62 to engage ashaft 63, which forms part of an Underwood carriage, and is journaled infixed bearings thereon. The hooks (32 may be held against outwardmovement lengthwise of the shaft 63 by sleeves 64 on said shaft, and arealso rigidly held against the usual inward movement along said shaft asthey bear against the ends 43 of the roll frame. That is to say, thearms 60 are securely held against endwise play or movement in eitherdirection relative to the roll frame, and endwise movement of the rollframe relative to the platen is also prevented. The webs are thusmaintained in a position normal to the platen.

The webs of paper from the rolls 41 are led forward over the rolled orheaded up per edge 65 of the paper shelf 20, which serves as anassembling guide for the webs, the latter being directed downward-overthe paper table and between the platen and the rear and front feed rolls66 andv 67, and thence upwardly past the printing line. The ribbon 38,above referred to, may serve for printing on the outer web, or on awork-sheet whlch may overlie the webs at the printing line. The printingon the other webs may be caused by carbon Webs wound or certain of therolls 41 or by any other suitable manifold material in any suitablemanner.

By having the axes of the rolls staggered or ofiset from each other inthe manner shown, it is possible to have the weight on the roll-carriageso low that there is little or no tendency for the roll-carriage to rockendwise, as would be the case were the rolls directly above each other.It is this having the weight low which largely makes possible the simpledetachable connection between the typewriter carriage and theroll-carriage.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
